FROM THIS EPISODE

African-American studies are alive and well in the high schools of Tucson. But the state Attorney General has declared Mexican-American studies illegal under a recent law. One piece of evidence is a textbook written long ago by a respected veteran professor at Cal-State Northridge. Does teaching that part of the US once belonged to Mexico mean advocating new borders? Does teaching the history of discrimination mean advocating resentment and racism in reverse? Also, in Silicon Valley, a computer museum. It's all about shrinkage. On our rebroadcast of today's To the Point, as President Hu Jintaou arrives tomorrow for a White House visit, the US and China are being compared to two aircraft carriers that can only be moved from the very top. We hear how both countries have been preparing and whether personal connections between the heads of state can resolve the increased tensions of recent years?

Dr. Rudy Acuña founded the Chicano Studies Department at California State University Northridge. At 78, he still teaches in what's become the largest program of its kind in the nation. In 1972, he wrote Occupied America: A History of Chicanos. The book has now been cited as an example of what's wrong with Mexican-American studies in Tucson, Arizona, which have been declared illegal by the state's newly-elected Attorney General, former Superintendent of Schools Tom Horne. We talk with Professor Acuña and others.

Computers are only about 50 years old, but that's old enough to give them a museum — where else but in Silicon Valley. Actually, the effort began 30 years ago on the other high-tech corridor, Route 128 around Boston, Massachusetts. But the permanent opening of the Computer History Museum was last Thursday in Mountain View, north of San Jose. Scott Ard is editor-in-chief of the technology website CNET.

President Obama and Chinese President Hu Jintao will have a small, private dinner tomorrow with top aides. Wednesday, they'll attend the third full state dinner of Obama's term, an honor Hu was denied by George W. Bush.
